Those are the cars that were shot to pieces by Israeli helicopters as part of the Hannibal Directive, which is an IDF doctrine that says they should kill their own citizens to prevent them being taken hostage. On Oct 7th, a large number of Israelis were fleeing the music festival in their cars and were killed by the IDF. IIRC the Israeli government later crushed all the cars before anyone could investigate them and confirm this, as it's obviously a bad look to slaughter your own civilians.
